0bjective：To explore the relationship between volume of PAT and coronary artery atherosclerosis and metabolic risk factors in more than sixty years old patients．Methods：483 olders of more than sixty years who underwent 64 slice CT were studied．They were in-patient or have healthy check-up files. 223 patients who underwent Cardiac multislice computed tomography．Multislice computed tomography was used to measure PAT volume and coronary artery calcium score. Patients were divided into coronary artery disease(CAD)and non-CAD group based on the presence of≥50％ stenosis or reached clinical diagnosis standard. The patients were grouped according to the number of metabolic risk factors，then PAT volume was compared among the groups．Results：PAT volume was not significantly higher in patients with CAD than that in non-CAD subjects[(190.9±69.24)cm3 vs(185.72士53.01)cm3，P＞0.05]．As the number of metabolic risk factors increased，the volume of PAT increased correspondingly，but not significant difference among the groups(P>0.05)．Conclusion:For more than sixty years olders，MDCT measurement of pericardial adipose tissue volume can not be applied as one of the indicators of coronary artery disease.
